  15  * TODO:
  16  *
  17  *  - Go through all the config options and ensure they can all be
  18  *    configured and reconfigured properly.
  19  *     + icon title appears to be a non-option on Unix.
  20  *     + Why the hell did I faff about disabling two of the vtmode
  21  *       options? The rest aren't used either in pterm! Work out
  22  *       whether they should be, and how they can be.
  23  *     + Refresh in the codepage combo is badly broken.
  24  *     + `Don't translate line drawing chars' ?? What is this crap?
  25  *       It does nothing at all, and where's the option to paste as
  26  *       lqqqk? What was I smoking?
  27  *
  28  *  - Better control of the individual config box features.
  29  *     + SSH packet logging shouldn't be mentioned in pterm, and in
  30  *       fact not PuTTYtel either.
  31  *     + Keepalives, and the Connection panel in general, shouldn't
  32  *       crop up in pterm. (And perhaps also not mid-session in
  33  *       rlogin and raw?)
